IDSL
Description
IDSL is a new service based on DSL (Digital Subscriber Loop) technology that uses existing copper cables to deliver high speed data access to the Internet.  IDSL services are being offered in a Residential and Business class of service.

To choose the service option that meets your needs you will need to decide on either Residential or Business service and the Port and CIR that you would like.

Port - This is the maximum speed of the connection.

CIR - Committed Information Rate is the data rate that you are guaranteed to get regardless of the network load.   Generally you will be able to burst to your port speed but when there is network congestion you will always be guaranteed your CIR.
